The machineof our invention comprises ,a-liiaed supporting base, 20, anda carrying .frame mounted to rot-ate on a v eticalaxis supported by. the base. In the preferred embodiment of the machine here shown, the carrying frame includes a'turntable 21, and a superstructure fixed to andv vprojecting above the turntable, and including horizontal, bars 22, having bearingsf23 '(Figures' a and 4). '.Invsaid bearings are j'ou'rnal'edvertical spindlesv 24, which are l'providedwith terminals 25 Figure', 5 ),.on which articles v to be cooked vor toasted 4may-'be confided,'the

terminals being removably in serte' l i`nv sockets 32 in the spindles.

The vertical axis of, the carryingiframe is preferably .provided by a verticalgsocket.

-, 26,- lixedand projecting .above the base2l),

a fixed vertical stud 27, secured as by a piu 28, in the socket'and projecting above the .1latter; and through the turntable 21, and a,

hub 29,-formed on the turntable and em-` bracing aportion of thestud.` anti-frio, tional thrust bearing 30 is interposed, between the socket 26 and,l the hub 29, and permits free rotation of the carryingframe on the stud. I

The spindles 25 are arranged in hollow vformation around the axis .ofthe frame, the spindles |,preferably` forming a hollow square, as shown by Figure`2.

We provide heating means'carried by the frame within the group of spindles, said heating means being arranged to act simultaneously on "the artic-les confined' 'on the spindles. We prefer to embody the heating means in a plurality of electrical heating units'33, carried by thel frame within thev i A -group of spindles and arranged in ,hollowv' "formation, as shown by Figure 2, said units presenting four sides, which-are 'uniformly spaced `from the rows constitutingthe hollow group of spindles.

multaneously moving' the frame and the spindles vand including lframe-rotating means yamil spindlerotatng iiiear.i. ,`l organ ized respectively to rotate the frame aboutv its axis and to rotate the spindles about their several axes, `so that the spindles have a planetary motion, the group of spindles revolving about the axis of the frame, and each spindle rotating about its own axis.

The frame-rotating means includes an electric motor 35, a vertical shaft 36, driven by the motor and provided with a friction pulley 37, and an annular friction flange 38, formed on the turntable 21, and in frictional engagement with the pulley, as shown by FigureS. The shaft 36 is journaled in a bearing 39, fixed to a movable base 40, having rolls 41' bearing on the fixed base 20. The base 40 is movable by a spring 42, in the direction required to press the friction roll 37 against the turntable flange 38, and is movable in the/opposite direction, against the stress of the spring 42, to disengage the frictionroll from the'flange, and thus stop. the rotation of the frame. To cause the lastmentioned movement, we provide a cam bar 43 (Figures 1 and 8) journaled in bearings 44- on the fixed base 20, and provided with an operating handle 45. Then said handle is moved in the direction of the arrow (Figure 1), the cam bar forces the movable base to the, left from the-position shown by Figure 1, and thus separates the friction l roll 37 from the flange 38. The' motor 35 is four interen mounted ony the movable base, and its shaft Yis connected with the friction roll shaft 36, to rotate the latter, by a belt 46, running on a. pulley 47, on the motor shaft, and on a pulley 48, on a shaft'49, journaled in bearings on the movable base. The shaft 49 has a bevel gear 51, meshing with a bevel gear 52. on the friction roll shaft 36. Elements of the spindle-'driving means are four horizontal shafts 53, arranged in hollow formation, corresponding to that of the spindles and connected end to end by bevel gears 54, a lbevel gear 55, fixed to the stud 27, a horizontal shaft 56, journaled in bearings'57 on the turntable, and pro-vided 'wit'ha gear 58, meshing with the fixed gear 55 and with a gear 59 meshing'with a gear v60', on one of the Shafts 53.'` i

I The arrangement-is suchV that when the frame isro'tated about the fixed gear 55, the 'gagcd horizontal shafts 53 are simultaneouslyrotated...

Other elements of the spindle-driving means are vertically arranged friction disks 61, fixed to the shafts 53. and horizontally arrangedfriction disks 62, fixed to the lower yspindle sections 24, and in frictional engagef ment with the' disks l61, the arrangement being such that the rotation of the horizontal shafts 53 and their 'disks 61, causes .the rotas tion of the disks 62 and the spindles. The disks 61 are preferably eccentric' to the .shafts 53, so that Vtheirrotation-1 not only rotates,y -but also vertically reciprocates the spindles,

the. lower sections 24 of which are vertically movable in the bearings 23. The object of the vertical reciprocation is to increase the spectacular effect of the machine when it is in operation, the spindles having an up and down motion, in addition to the planetary motion above described.

The spindles are spaced from the heating units 33,-so that articles'confined thereon are in close proximity to the units, without contacting with the latter. The rotation of the spindles causes all sides of the articles to be uniformly cooked or toasted. The spindle terminals 25 may be removed from the sockets of the spindles, thrust into sausages and then replaced. Each terminal 25 hasa drip cup 64, at its lower end portion, adapted to vcollect liquid flowing from an impaled steak may be confined and cooked between the sections 65. y

Figure 7 shows a terminal adapted to hold a slice of bacon. This terminal includes a shank V69, a drip cup 70, and a grid 1, fixed to the shank, and a grid 72, lhinged at 473 to the grid 71, and adapted to be confined against the latter by a catch 74.l

The frame superstructure may be of any vsuitable construction adapting it to support the heating units 33 in the hollow formation, and in the location relative to the spindles shown by Figure 2. Said units are preferably looped. as shown by Figure 1, and insrted in orifices in frame bars 76 (Figure Inward radiation of heat from the heatin units may be prevented by. wall members 7 of asbestos board, or other suitable material. The heating units may be externally protected by sheets`78 of wire cloth, located between the outer sides of the heating units and the spindles.

To supply current to the heating units we provide conducting wires 80, connected with a source of power G, as shown by Figure 11. The wire 8OV is connected with an annular contact member or ring 82, and the wire 81 is connected with an annular contact member or ring 83. Said annular members are fixed to and insulated from the fixed stud 27. Spring contact members 84 and 85 secured to members of the rotary frame, as shown by. Figure 10, contact respectivelywith the an# nular members 82 and 83,-andv are connected by circuit wireswith the heating units, as

indicated diagrammatic'ally by Figures 11,'

v heating circuit and are adapted to be adjusted ,as shown by Figure 11, to cause a low heat, and as shown by Figure 12, lto cause 'a medium heat, and as shown by Figure 13,l to cause a-high or maximum heat. V

Figures 14 and 15 'show a modification, in which the'rotary frame includes a hub portion 88, rotatable in ahorizontal plane, on a fixed stud 89, on a fixed base 90, tubularl arms 91, radiating. from the hub portionslides 92 movable in the bores of the arms 9.1,''and pressed outwardly therein by springs 93. On the outer ends of the slides 92-are grooved pulleys 94, to Whichv'are fixed -vertical im-paling spindles 95. The pulleys '94`are pressed bythe Isprings 93 against a horizontal annular track 96,supporteii by standards 97, fixed to the base 90. The shaft 98 of a motor 99, fixed to the base, is connected with the hub portion 98, by a bevel gear 100, fixed to the motor shaft, and abevel gear 101 fixed to the hub 88. The motor therefore rotates the frame and the annular track 96 in frictional contact with the spindle pulleys 94, causes the rotation of the spindles o'n their several axes, the spindles having a planetary motion` as before. rIfhe heating element (not shown) will in thisY case, bean-l nular and suitably spaced from-the inner sides of the spindles.
